Known Issues with Power Management
This hotfix resolves the problem that is described in the "Symptoms" section of this article. Note that you may experience some issues that involve computer power management after you apply this hotfix. These issues are described later in this article. Most of these issues are caused by drivers from the Independent Hardware Vendor (IHV) or Original Equipment Manufacturer (OEM) for your computer's hardware. This hotfix causes USB devices to work correctly, which may expose problems in the IHV or OEM driver. If you experience any of the following issues, contact your hardware manufacturer to inquire about obtaining an updated driver.
Known Issues with Power Management and IHV or OEM Drivers
- USB devices may start working correctly (they are enumerated and work as expected) with the hotfix applied, but the vendor drivers for a USB device may not permit the computer to resume from hibernation or standby.
- In some cases, the computer may resume from hibernation or standby, but you may see a USB Device Unsafe Removal dialog box after the computer resumes.
- If you remove the USB device cable (or if you unplug the device from the computer), the vendor device driver may cause the Device Manager tool to stop responding (hang). If this occurs and you restart Device Manager, the USB device is listed in the device list even though you unplugged the device.
- When you unplug a USB device, you cannot use the device again until you restart the computer. If you plug the USB device in again without restarting the computer, Device Manager cannot detect the device because of possible problems with the vendor USB drivers.
